NAME

t_unbind − disable a transport endpoint

SYNOPSIS

cc [ flag ... ] file ... −lnsl [ library ... ]

#include <xti.h>

int t_unbind(int fd);

DESCRIPTION

This routine is part of the XTI interfaces which evolved from the TLI interfaces.  XTI represents the future evolution of these interfaces.  However, TLI interfaces are supported for compatibility. When using a TLI routine that has the same name as an XTI routine, a different header file, tiuser.h , must be used.  Refer to the section, TLI COMPATIBILITY , for a description of differences between the two interfaces. 

The t_unbind() function disables the transport endpoint specified by fd which was previously bound by t_bind(3N).  On completion of this call, no further data or events destined for this transport endpoint will be accepted by the transport provider.  An endpoint which is disabled by using t_unbind() can be enabled by a subsequent call to t_bind(). 

VALID STATES

The only legitimate state (see t_getstate(3N)) for a call to this routine is T_IDLE .

RETURN VALUES

t_unbind() returns:

  0 On success. 

−1 On failure. 

On failure, t_errno is set to indicate the error, and possibly errno is set. 

ERRORS

On failure, t_errno is set to one of the following:

TBADF The specified file descriptor does not refer to a transport endpoint. 

TLOOK An asynchronous event has occurred on this transport endpoint. 

TOUTSTATE The communications endpoint referenced by fd or resfd is not in one of the states in which a call to this function is valid. 

TPROTO This error indicates that a communication problem has been detected between XTI and the transport provider for which there is no other suitable XTI t_errno value. 

TSYSERR A system error has occurred during execution of this function, errno will be set to the specific error. 

TLI COMPATIBILITY

The XTI and TLI interface definitions have common names but use different header files.  This, and other semantic differences between the two interfaces are described in the subsections below. 

Interface Header

The XTI interfaces use the header file, xti.h .  TLI interfaces should not use this header.  They should use the header:

#include <tiuser.h>

Error Description Values

The t_errno value that can be set by the XTI interface and cannot be set by the TLI interface is:

TPROTO
